Personality

Eraser is generally grumpy, bored and impatient. He doesn't speak much unless necessary. In his spare time, he usually sits around without interacting with anyone except Pen, unless it's necessary. His voice is low-pitched and unenthusiastic. His eyes are usually narrowed to express apathy or boredom.

He can be quite arrogant, making Pin believe he thinks that he is too cool to do anything. He also says his famous catchphrase: "WHICH IS?!" in multiple episodes when Announcer is announcing the next contest.

In BFB, Eraser seems to be somewhat more enthusiastic and helpful, while still retaining his grumpiness, and just like Pen, Eraser expands his group of friends by joining a team with characters he had never interacted with before.

Battle for Dream Island

In "Take the Plunge: Part 1", Eraser is talking to Pen about how annoying and uncool Woody is. He is also seen talking to Blocky, agreeing with how bossy Golf Ball was, calling her a "bossy bot". He wishes he could get away from her, Flower, Woody and Spongy. The Announcer then comes down telling him about Dream Island. After hearing about it, Eraser wants to buy it, but the Announcer keeps on telling him the others would want it too, therefore they must compete for it. During the balance beam challenge, he is quickly pushed off by Flower and falls into the water, losing the challenge.

In "Take the Plunge: Part 2", Eraser is one of the last few chosen but Pin chose him because despite her thinking he thought he was to cool to do anything, she thought he was the "least horrible" out of the others not chosen. Eraser and Pen both pick Blocky on their team, though Match isn't happy about this. When building the boat for the next challenge, Eraser steps on a nail and screams. He then starts flowing into the air before landing on more nails.

In "Barriers and Pitfalls", before the challenge, the Announcer says that he has to tell the Squishy Cherries something before starting, much to Eraser's boredom. After Announcer tells them that they are missing a member, he and Pen quickly realise it's Blocky, who had been assumed to be eaten by a Fish Monster last challenge. They both volunteer to find him. After finding Blocky, who actually wasn't eaten by the monster, and after freeing Pencil from said monster's tongue, they get back to running across the obstacle course. Eraser quickly falls into a pit and stays in the Failer's Waiting Room for the rest of the episode. His team loses the challenge, putting him and the rest of the team up for elimination.

In "Are You Smarter Than a Snowball?", it's shown that he loves all kinds of cake, as seen when Eraser eats Key Lime Pie as a prize for being safe and saying "All cake is good cake", despite Match not liking it. During the test challenge, Blocky finds the test answers and Eraser tells him to high five. However, Blocky hits him so hard that Eraser flies away and ends up landing in the hole that Woody created by falling. He stays there for the rest of the episode. His team loses again and is put up for elimination.

In "Sweet Tooth", Eraser and Pen are both safe and get each a piece of an ice cake (which is just chunks of ice) a prize. However, the chunks are flung at them, and they get launched across the horizon. When the Announcer explains the challenge is a cake baking contest and the cakes would be judged by him, Flower and "the magical die of judgement" Eraser points out that it's just a normal die. He and Pen both realise that Leafy is making a big cake, and she says it so if anyone is having trouble, she could lend some of it to them. They then want some of her cake, but they need five dollars each. Pen already has eight dollars and they find a $1.99 bill but they're one cent off, so they pick up Coiny in an attempt to pay for the cake. They are then angered when they see Leafy about to offer Woody a cake for free. When getting his cake judged, he gets 7 from the Announcer, which was a point less than Bubble who also bought some of Leafy's cake. He gets a 10 from Flower, much to his happiness, but a 1 from the die, much to his disappointment. He is later seen with some of the contestants eating chocolate balls, but his team eats them slower than the Squashy Grapes. Because the Squishy Cherries won one challenge and the Squashy Grapes won another, the Announcer settles who wins with a tiebreaker, which the Squishy Cherries lose, putting them up for elimination again.

In "Bridge Crossing", Eraser is safe from being eliminated once again. During the bridge crossing challenge, he pushes Bubble on to bridge, wanting her to cross it. When the bridge breaks due to Snowball throwing Rocky at it, he wonders how they are going to get to the other side. Pen then sees another bridge, but it is then taken out by Snowball removing the sticks holding it so he can throw Tennis Ball down. Pen proposes to cross the bridge by climbing on the rope railings. Despite Pen's enthusiasm to do this so they can win, Eraser doesn't want to do it, so he tells him to go first. However, while Pen is climbing, Eraser realises that the ropes are just bendy straws attached to tapes, and they collapse, causing Pen to fall. The Announcer then notices that there is no other way to get to the side, so he starts another tiebreaker, which the Squishy Cherries lose again and get put up for elimination because of it.

In "Power of Three", Eraser is in the bottom three for Cake At Stake and is set-up with a math problem (sort-of) leading up to the speaker falsely telling him he is eliminated with 9 votes when he only has 2. Before Pin is flung into the TLC, she grabs Eraser stating that the team needs a heroic leader like her. When she is flung, she lets go of Eraser, who lands on Bubble, popping her. For the challenge, everyone is put into a group of three and Eraser is with Pen and Firey. While running across the balance beam, Firey falls off into the water. Pen tells Eraser that he must have died from touching it and Eraser says they have to go to the Firey Recovery Center and turn it on to recover him. When they get there they find out they have to wait until it warms up before Firey's recovered. When he's recovered, Eraser tells Firey not to fall off. They end up catching up to the others and are actually the first to get to the finish. They all get a Win Token before being sprung out of the building and into the air. Eraser, Pen and Leafy are all seen still flying through the air.

At the start of "Puzzling Mysteries", Pen shows Eraser that he can spin a basketball on his finger. Eraser says he's better and spins three basketballs on his finger, much to everyone's praise. He asks Needle how many she can do, but he calls her "Needy", causing her to slap him. When the Announcer is introducing the next challenge, Eraser wants to know what the challenge is. During the puzzle challenge, the Squishy Cherries look at the pieces from the other side. Pencil thinks they may looking at it wrong, but Eraser says that she was worrying to much. Match and Pencil are later talking about how Eraser stood on a nail in Take the Plunge: Part 2, to which Eraser tells them that they better not be talking about him and should finish the puzzle. Match thinks he's as bossy as Pin because of this. When Pen finally finishes the puzzle (in the episode's stinger) Eraser can be heard saying "It's about time!"

In the "Cycle of Life", Eraser is shown in the Blocky's Funny Doings International commercial, where he sets up the Ice Cube prank. When the Announcer says that the team which wins this challenge gets a prize, Eraser wants to know what the prize is, only to hear that he'll find out later, much to his annoyance. During the challenge, Eraser has to carry Pen on his back while running. Bubble (who gets popped and is recovered far away from the racing area) doesn't finish before Rocky (who actually mostly got across by Golf Ball kicking him) and therefore makes the Squishy Cherries lose. Eraser is angry at her for this.

In "Insectophobe's Nightmare", Eraser once again asks what the challenge is just as it's being introduced. There is a silence after this and Eraser has a big frown. During the six-legged race challenge, Eraser tells his team to look out for the tree, which they all do, except for Pen, who is being dragged across the ground and smacks his head on the tree. His team wins the challenge.

In "Crybaby!", Bubble is happy that they won the last challenge, though Eraser says that her talking slowed them down and they nearly lost because of that. The Squishy Cherries get a choice of either Snowball or Teardrop on their team. Eraser is the first to choose and he chooses Snowball, calling him awesome. During the crying contest Match asks him why he isn't crying, his reply being that crying is for wimps. The tiebreaker challenge is a skiing challenge, but both the Squishy Cherries and Another Name trip over Rocky and roll down the hills as snowballs. At the finish, one snowball places first and the other is placed last. Because the Announcer couldn't tell which snowball was which, he starts another tiebreaker: a hand-standing contest. Another Name quickly loses the challenge, while all the members of the Squishy Cherries are still hand-standing. Then Rocky vomits near the team, causing all the members to slip, except for Eraser who jumps away on his hands and tries to blow the vomit away. Because he is the last one standing, he gets a second Win Token. He is happy about this until he hears that he can only use one token at a time.

In "Lofty", the Cherries get to choose between Rocky or Golf Ball to be on their team. Eraser chooses Rocky because he thinks Golf Ball is too bossy, bringing back the nickname of "bossy bot". During the challenge, Snowball pops Pencil's balloon, despite being on the same team. When Eraser asks why he did it, he says that the balloons were pink and therefore too girly for him. Eraser disagrees, saying that pink was quite manly. Snowball and Eraser both throw numerous nails at Leafy but she dodges them all. Eraser's balloon is popped when Leafy squeezes it.

In "A Leg Up In The Race", during the ladder climbing challenge, Eraser is first until he gets hit by a water balloon making him fall down. He makes it to the top in 8th place. When the point platforms push up due to everyone getting 30 points, Eraser is one of the only ones not to scream (the others being Pen and Rocky). When the Announcer says that there will be no more Win Tokens, Eraser asks what happens to the two he already has, which get converted into 15 points per token. Because he had the most tokens, Eraser has the most points with 60. He then gets some points for his place in the challenge, but is overtaken by Pen and Blocky. He loses 3 points because he had received 3 votes throughout the game.

In "Don't Lose Your Marbles", Eraser once again asks what the contest is when it's being introduced. Because of this, the Announcer calls him impatient or "imp" for short, with Match agreeing. At first Pen and Eraser can't find any balls, but later it is revealed that Eraser had found a ball, along with Blocky. They both turn the balls in, but Eraser loses points because it was maroon instead of red. He claims that the two colors are the same but he still has find another one. By the time Eraser finds another ball he is the last one and it has become dark. When Eraser shows the Announcer his ball, he thinks it's maroon, but can't tell because it's dark. Eraser grabs Firey to light up the area, but the ball catches on fire, so he still can't tell. The Announcer counts the ball, but Eraser only gets one point being the last one to hand in a ball. Despite gaining the least amount of points in the challenge, his score doesn't fall into the bottom four, so he is safe from elimination.

In "Half a Loaf Is Better Than None", Eraser is seen at the start daring Pen to jump over a gap. Pen does this easily, but when Eraser tries he nearly falls into the gap, grabbing onto the cliff. He calls Pen for help, but he nearly falls down, and he calls for Blocky. The cycle of everyone nearly falling down continues until Leafy calls for Ice Cube, who gets revenge by helping not her and making them all fall down. For reaching the halfway point of the competition, everyone gets half a pair of scissors. During the rejoining challenge, Eraser, Pen and Blocky cheer Snowball on. Eraser, along with many other contestants fall into a vat of hydrochloric acid in an attempt to find the marbles the Announcer dropped in there for bonus points. The Announcer also gives bonus points to all the armless contestants. In an attempt to gain more points Eraser tries cutting off his arm with a knife before Leafy tells him not to even think about doing so. When Pen asks what the challenge is as it's being introduced, Eraser tells him that he's using his line. The challenge is a hurdle jumping challenge, but Eraser gets knocked over by the first one. Eraser ends up in the bottom four and is put up for elimination.

In "Vomitaco" while Leafy is hoping Ice Cube isn't eliminated, Eraser interrupts her saying "whatever", to her annoyance. He is eliminated as he receives 99 votes, which was 66 more than Ice Cube, who had the second most. When the Announcer gives the remaining contestants the other half of the pair of scissors, there is a cut to the TLC, where Eraser is sighing that he only has half a pair. He is then referenced when Pen asks what the challenge is and said he was filling in for Eraser by asking. In the episode's stinger, Eraser suggests that they won't be getting anymore tacos.

In "Reveal Novum", the eliminated contestants try to escape the TLC by pushing it while it's top is open. However, as they're pushing it, it bounces off the springy shoes which Bubble threw away and falls into the bottom of the lake. The TLC then starts to leak and starts filling up with water. Coiny thinks that they're all going to drown, which Eraser simply responds with "Oh well". Coiny angrily asks what he means by this, and Eraser thinks that they could just press the emergency button to call a rescue team. He starts panicking when he learns there is no such thing. The TLC is eventually lifted up by the sun.

In "Gardening Hero", it is revealed that the viewers can vote on which eliminated contestant could rejoin the game, and they each get a rejoining audition. During his audition, Eraser presses a button multiple times, and states that the rejoin button isn't working.

In "The Glistening", before seeing who gets to rejoin the game, the eliminated contestants got to vote on who to eliminate in the episode. After Snowball votes Ice Cube, saying that she'll cool down the TLC, everyone else votes for her, with Eraser stating that the heat there is almost unbearable. Eraser and Pen got 2 to the fifth votes, which Eraser says "which is" to, before finding out that it's 32. This wasn't enough to rejoin so Eraser is sent back to the TLC.

In "Return of the Hang Glider", Eraser is seen talking to Pen inside the TLC about what would happen if you took the first spoken word of the first episode, second spoken word of the second episode, and so on until the 25th episode. When voting on which of the remaining three contestants they want to win Dream Island, Eraser, along with many others vote for Leafy, and slap anyone who votes for anyone else. Firey ends up winning Dream Island and decides on who to let into the island. Snowball asks if he, Eraser, Blocky and Pen were allowed in, which they were. However, Leafy, who was the only one not let in, buys Dream Island for herself. When the Announcer says that he sold it, Eraser tells him that he can't just sell it. When Pen asks if he's the only one who wants Dream Island after all this time, Eraser responds with him wanting Dream Island. Pen says that he has a brain because of this, which he contradicts by saying erasers don't have brains. Eraser and some other contestants ask Leafy is she's seen Dream Island, with Eraser saying that Firey deserved it. When Leafy says that Firey never got Dream Island, the others want to know how she knew that. Leafy uses the excuse that she heard it through the walls but Eraser states that said walls are soundproof. After figuring out Leafy has Dream Island, Golf Ball says it's time to find out what's inside her, to which Eraser and Pin rip Leafy in half, revealing Football. Before Leafy gets crushed, Golf Ball asks if she has any last words. She is about to say something, but is interrupted by Eraser pressing the button to activate the crusher.

Battle for Dream Island Again

In "Yeah, Who? I Wanna Know", he got 185 votes to join and was placed 26th, which was not enough to join. When Book comes across a sheet of paper explaining the BFDIA rules, Eraser snatches it and starts to read them to everyone. Eraser misinterprets that all contestants not competing must be killed, and there is a hallucination of him and everyone else not competing being crushed. However, he realises that it said that the contestants would be locked up in the TLC, and he and everyone else was flung to the TLC, which was then flung into the LOL.

Battle for BFDI

In "Getting Teardrop to Talk", Pen shows Eraser that he found a "rectangle", but Eraser corrects him, saying that he actually found a parallelogram and he "would know" (because his body is shaped like a parallelogram). After that, Pen shows him a pentagon. Eraser then fearfully explains to his friend that pentagons are "extremely scary". Eraser and Pen scream when the pentagon makes an ominous noise. He and Pen are relieved when Blocky uses Saw to cut the parallelogram into a quadrilateral and a triangle. When Four appears and asks everyone if they want to battle for a prize, no one responds except for Eraser, who asks what the prize is. When contestants begin to form teams, Pen wants himself, Eraser, and Blocky to stick together so that they could all be on the same team, and Eraser agrees with him. However, after Yellow Face takes one of Fries' fries and shouts out that there's free food, Eraser quickly forgets about his friends and runs to him. When he gets there, he asks Yellow Face where the free food is, and the repetition of the words "free food" between the two of them eventually causes the team name to be Free Food. When the teams are all selected, Eraser asks if it's time for the first challenge before realizing he wasn't near Blocky and Pen anymore.

In "Today's Very Special Episode", he is first seen with Bell asking to where her string leads up to. She refuses to tell him, so Eraser climbs up her string to find out for himself, much to Bell's discomfort. It isn't long before he is joined by several other contestants also curious about Bell's string. He keeps climbing until Lightning zaps Bell, causing the shock to go up her string and shock everyone climbing her string, including Eraser. He is later seen trying to get Four's attention, but since Four had previously consumed and excreted Beep's cake, Eraser accidentally steps in his excrement. When Marker shows off The Year's Hottest Look, Eraser was hit by one of Four's Love Hearts and was launched into the horizon.

In "Questions Answered", Eraser doesn't do much. However, his team is found out for cheating in the test so they are up for elimination.

In "This Episode Is About Basketball", X hosts Cake At Stake, but he accidentally reads the votes backwards. This leads to him thinking that Eraser and Foldy were in the bottom two, but were actually the first two safe. When Stapy gets eliminated, Eraser seems mildly disappointed. Afterwards, Eraser tells X that reading the votes backward was the best April Fools prank ever, and when X admits that it wasn't intentional, Eraser seems unfazed.

In "Enter the Exit", Foldy is recovered and asks where Stapy (who has now been sucked up by Four) is. Eraser then shows footage of Match showing the footage of them cheating in "Questions Answered" to Donut, as an explanation of how Stapy ended up eliminated.

In the start of "What Do You Think of Roleplay?" Eraser, Blocky and Pen all discuss what they've been doing since they separated for teams. Blocky mentions that he plans to do another prank and Eraser says he can him help him. Pen then compliments Eraser of how tolerant he's been. Eraser asks what he means, and he tells him that Foldy looks like a pentagon. When Eraser notices this, he starts to scream, until Ruby unfolds her for revenge of the last episode. He thanks Ruby for this, raising his hand and starting the intro. During the challenge, Eraser suggests Fries folds back Foldy so they can find out who's the fake on their team. When the fake is revealed, he tells Fries to stop folding her back because she'll be a pentagon again, but he thinks there are many problems with what he said. In the episode's stinger, Eraser is walking but stops when he sees Ruby. He realizes that she also looks like a pentagon and starts screaming.

Deaths

Trivia

Running gag: Eraser says "Which is!?" constantly before the Announcer announces a contest. The most recent time he said something similar was in Get to the Top in 500 Steps, in which he asks “So what's the contest?”
